Question

Before happening the "big bang" explosion, what's thing out of the thing which cause explosion?

Answer 1

Forty-two.

Answer 2

Are you asking what caused the Big Bang explosion?  

Nobody knows.  The laws of physics break down at that point.  There is no way to know what caused it, or what happened before it.

Answer 3

According to the Big Bang model, the universe expanded from an extremely dense and hot state and continues to expand today. A common and useful analogy explains that space itself is expanding, carrying galaxies with it, like raisins in a rising loaf of bread. General relativistic cosmologies, however, do not actually ascribe any 'physicality' to space.

Answer 4

Did you know that the matter in your body is billions of years old?

According to most astrophysicists, all the matter found in the universe today -- including the matter in people, plants, animals, the earth, stars, and galaxies -- was created at the very first moment of time, thought to be about 13 billion years ago.

The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.

The Big Bang was like no explosion you might witness on earth today. For instance, a hydrogen bomb explosion, whose center registers approximately 100 million degrees Celsius, moves through the air at about 300 meters per second. In contrast, cosmologists believe the Big Bang flung energy in all directions at the speed of light (300,000,000 meters per second, a hundred thousand times faster than the H-bomb) and estimate that the temperature of the entire universe was 1000 trillion degrees Celsius at just a tiny fraction of a second after the explosion. Even the cores of the hottest stars in today's universe are much cooler than that.

There's another important quality of the Big Bang that makes it unique. While an explosion of a man-made bomb expands through air, the Big Bang did not expand through anything. That's because there was no space to expand through at the beginning of time. Rather, physicists believe the Big Bang created and stretched space itself, expanding the universe.

Answer 5

I used to play the silly "say anything but God" game, but guess what? I was wrong! If you truly understand quantum mechanics then you will know that the Big Bang theory requires a creator by fiat. Think of the universe in reverse until it's small enough to be completely described by quantum mechanics alone. In order for the universe to start unfolding into what we see now, our universe's specific wave function had to be brought into existence as a certain possibilty out of an infinite number of other possible wave functions that had to collapse or at least decohere. At this fuzzy nanoscopic beginning, this required a 'Prime Observer' to enable this and set the expansion of the universe into motion and those initial conditions became the very facets of physical law. What we refer to as this finely tuned 'reality'. This need for an 'observer' comes from the basic quantum mechanical concept known as Shrodinger's Cat. Also, we must remember that the universe is being said to have come from nowhere which implies an act of 'creation'. This expansion of the universe is also alluded to 11 times in the Bible:  Job 9:8 ; Psalm 104:2 ; Isaiah 40:22 ; Isaiah 42:5 ; Isaiah 44:24 ; Isaiah 45:12 ; Isaiah 48:13 ; Isaiah 51:13 ; Jeremiah 10:12 ; Jeremiah 51:15 ; Zechariah 12:1

The Bible also alludes to the soon to come Big Rip:

Revelation 6:14 ; Isaiah 34:4 ; 2 Peter 3:10

Answer 6

Nobody knows, sadly.

But it's fun to think about! Probably the safest answer, given the current state of human knowledge, is "undefined".

You can come up with all sorts of tricks to answer the question, but you'll find there's always a "before" or "outside" that you have to account for.

For example, you might want to think of the universe as "finite but unbounded". By which I mean that the universe is of a finite size, but you can travel infinitely in straight line without ever hitting an edge or leaving the universe.

How can that be? Only if space is curved in some dimension that we can't perceive. It's easy to think about if you imagine an ant on a basketball. The ant can walk in a straight line, and eventually he'll end up where he started. To the ant it seems like he's walking on a flat plane in a straight line (he's too small to notice the curvature of the basketball), but we know better.

Is the basketball "infinite"? Of course not - it's just a basketball. But the property of curvature means that it can be perceived as infinite in some aspects (such as the ability of an ant to walk forever in a "straight line" - I use quotes because of course to us the line isn't straight...)

Einstein predicted the curvature of space, and it has been experimentally verified (google "gravitational lensing"). So we know that space is curved in some sense. It's certainly possible that there's additional dimensions that we can't perceive.

But if the universe is finite, then there must be an outside, right? Even if it's curved on itself in some complex, 11-dimensional way - there's still must be an outside!

Or maybe the universe is infinite... in which case how did it get all squashed together at the moment of the big bang, and what existed apart from this tiny dot of universe? And what existed right before that point?

Undefined.

Sorry.

Answer 7

Its possible our universe formed from a previous universe which experienced a "big crunch" This happens when there is enough mass(and therefore gravity) in a universe to override the inflation of the universe. Fortunately, our universe doesnt have enough mass to experience a "crunch".

Answer 8

Wow, lots of fine answers with long words to say "Dunno."  

First, understand that there was no "explosion" in the usual sense.  Second, the term "Big Bang" you may be interested in knowing, was first used by astronomer Fred Hoyle, who opposed the theory and who used the term to ridicule the idea.  The name caught on, mostly I think because there wasn't a better term to use.

Third, I'm not sure there was a "before", as difficult as that is to get my mind around.  It's not easy to think about "nothing", either in terms of "no objects" or "no time"...just "no nothing...complete void"...wow, it blows my mind just writing about it.
